Downfall

# Downfall with AMD Ryzen 5 5600 + NVIDIA GeForce RTX 5080

The pairing of AMD's Ryzen 5 5600 with NVIDIA's RTX 5080 produces a fascinating split in Downfall: at 1080p the frame rates are astronomical, but they collapse hard at 4K Ultra. The data shows a system that is GPU-bound at lower resolutions but becomes increasingly CPU-limited as pixel count climbs—a classic sign that the 6-core Zen 3 processor is holding back the Blackwell flagship in this horror title. With measured averages ranging from 363.5 FPS at 1080p Low down to 77.3 FPS at 4K Ultra, this combo delivers playable performance across the board, but the scaling pattern reveals where the bottleneck truly lives.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings, but the shape of that curve tells a clear story. At Low settings, the average falls from 363.5 FPS at 1920x1080 to 304.5 FPS at 2560x1440, then to 187.9 FPS at 3840x2160. That represents a 48.3% reduction from 1080p to 4K at Low. At High settings, the drop is even more pronounced: from 286.5 FPS at 1080p down to 205.7 FPS at 1440p, and finally 126.9 FPS at 4K—a 55.7% decline from the lowest to highest resolution.

The Medium preset follows a similar pattern, going from 336.9 FPS at 1080p to 250.2 FPS at 1440p and 155.1 FPS at 4K. Ultra is where the scaling becomes most dramatic: 179.4 FPS at 1080p drops to 130.2 FPS at 1440p, then plummets to 77.3 FPS at 4K. The 1080p-to-4K gap at Ultra is 56.9%, the largest of any preset. This suggests that Ultra settings are pushing both the GPU's shading workload and the CPU's draw-call limits simultaneously, creating a compounded bottleneck.

Notably, the gap between 1080p and 1440p is much smaller than the gap between 1440p and 4K at every setting. At High, the 1080p-to-1440p delta is 80.8 FPS, while 1440p-to-4K is 78.8 FPS. At Low, the deltas are 59.0 and 116.6 FPS respectively. The larger 1440p-to-4K delta at Low settings indicates that the RTX 5080's raw rasterization power is being constrained by the Ryzen 5 5600 at 1440p, but at 4K the GPU finally becomes the limiting factor. The data points to a system that can push very high frame rates at 1440p and below, but the 4K Ultra result of 77.3 FPS shows the CPU holding back what the GPU could otherwise deliver.

How This Combo Ranks

This specific combination ranks 89th out of 1,741 tested combos in Downfall, placing it in the top 5.1% of all pairings. That rank reflects the raw capability of the RTX 5080, which sits in the 89th percentile of all GPUs in the benchmark database. The Ryzen 5 5600, meanwhile, holds the 79th percentile among all CPUs. The combo rank of 89 is slightly below the GPU's individual percentile, which aligns with the CPU's lower standing—the processor is the weaker link in this pairing.

Looking at the CPU's nearest rivals, the Ryzen 5 5600 posts an average benchmark score of 21,765. It sits just 0.6% above the Intel Xeon D-1746TER (21,635) and 0.6% below the AMD EPYC 9554P (21,899). The gap to the Intel Core i7-11700F is slightly larger at 0.9%, with that chip scoring 21,957. These are all within a 1.5% band, meaning the 5600 is competitively positioned among its immediate peers, but none of these rivals are gaming-focused processors—they are server and workstation parts. For Downfall specifically, the 6-core/12-thread configuration is what matters, and the data shows it capable of feeding the RTX 5080 at 1080p but struggling to maintain that pace at 4K Ultra.

The GPU's rival comparisons are more telling. The RTX 5080's average benchmark score of 59,188 puts it 1.6% above the Intel Arc A570M (58,239), 2.5% above the Intel Arc A580 (57,756), and 2.6% above the AMD Radeon Pro W5500X (57,661). It trails the Intel Arc Pro A60 (60,326) by 1.9%. These deltas are small, but the RTX 5080's 89th percentile GPU standing combined with the 79th percentile CPU explains why the combo ranks 89th rather than higher—the processor is dragging down an otherwise top-tier graphics card.

Q: Is the Ryzen 5 5600 holding back the RTX 5080?

A: Yes, particularly at lower resolutions. The 1080p Low result of 363.5 FPS versus the 4K Ultra result of 77.3 FPS shows a 4.7x difference, but the CPU's 6-core/12-thread configuration and 3.50 GHz base clock limit how fast the GPU can be fed, especially at Ultra settings.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. Low settings produce an average of 363.5 FPS, Medium comes in at 336.9 FPS, High drops to 286.5 FPS, and Ultra bottoms out at 179.4 FPS. The spread between Low and Ultra at 1080p is 184.1 FPS, showing that the GPU has plenty of headroom and the CPU is the primary constraint. The 5600's 6 cores and 12 threads, running at 3.50 GHz base and 4.40 GHz boost, are able to keep up with the RTX 5080's demand at this resolution even at Ultra.

Moving to 2560x1440, the averages shift to 304.5 FPS at Low, 250.2 FPS at Medium, 205.7 FPS at High, and 130.2 FPS at Ultra. The Low-to-Ultra gap narrows to 174.3 FPS, and the Ultra result now sits below the 1080p High mark. This resolution still favors the GPU, with the CPU continuing to feed frames effectively. The 1440p High result of 205.7 FPS is particularly strong, suggesting this is the resolution where the combo feels most balanced.

At 3840x2160, the averages are 187.9 FPS at Low, 155.1 FPS at Medium, 126.9 FPS at High, and 77.3 FPS at Ultra. The Low-to-Ultra spread is now 110.6 FPS, much tighter than at lower resolutions. The 4K Ultra result of 77.3 FPS is the only sub-100 FPS number in the entire dataset, and it represents the point where both the CPU and GPU are fully saturated. The 4K High result of 126.9 FPS is the standout—it maintains a high refresh rate experience while preserving visual quality.

CPU Role

The Ryzen 5 5600 is a 6-core, 12-thread processor built on TSMC's 7 nm process, with a base clock of 3.50 GHz and a boost clock of 4.40 GHz. It features 64 KB of L1 cache per core, 512 KB of L2 per core, and a shared 32 MB L3 cache. In Downfall, this configuration proves sufficient for 1080p and 1440p gaming, where the measured frame rates exceed 286 FPS at High settings. The single-thread performance, reflected in the 3DMark single-thread score of 882 and Cinebench R23 single-core score of 2,584, is what drives these numbers—Downfall appears to favor strong per-core performance over raw multi-threading.

The CPU's multi-threaded capabilities are modest by modern standards: Cinebench R23 multicore scores 18,309, while PassMark multithread hits 21,541. These figures put the 5600 in the 79th percentile of all CPUs, but the data shows it is the limiting factor at 4K Ultra in Downfall. The 77.3 FPS result at 4K Ultra, compared to 179.4 FPS at 1080p Ultra, indicates that the processor cannot maintain the same frame-feeding rate as resolution increases. The 32 MB L3 cache and 51.2 GB/s memory bandwidth are adequate, but they don't compensate for having only 6 cores in a game that may scale beyond that.

The CPU's nearest rivals are all in the 21,600-21,950 average score range, and the 5600's 0.6% lead over the Xeon D-1746TER and 0.9% deficit to the i7-11700F show it is competitively placed. However, the i7-11700F has 8 cores, which may help in more heavily threaded scenes. For Downfall specifically, the 5600's 6 cores and 12 threads deliver strong performance at 1080p and 1440p, but the 4K Ultra result suggests the game's CPU demands outpace what this processor can offer.

Settings Recommendations

For 4K gaming, the High preset is the clear recommendation. At 126.9 FPS average, it clears the 120 FPS threshold and provides a smooth experience. Medium is also viable at 155.1 FPS, and Low pushes to 187.9 FPS, but High offers the best visual fidelity without sacrificing frame rate. The Ultra preset at 4K, at 77.3 FPS, is playable but will strain high refresh rate displays and may cause noticeable frame pacing issues in a horror title where smoothness matters.

At 1440p, High is the best choice with 205.7 FPS. This result keeps the system well above the refresh rate of most 144Hz monitors, and the visual upgrade over Medium (250.2 FPS) is worth the frame rate cost. Ultra at 130.2 FPS is also acceptable, but the 75.5 FPS drop from High to Ultra is substantial and not justified for most players. Low at 304.5 FPS is unnecessary unless chasing maximum frame rates for competitive play, which is uncommon in the horror genre.

At 1080p, High at 286.5 FPS is the sweet spot, delivering excellent frame rates with good visuals. Medium at 336.9 FPS and Low at 363.5 FPS are overkill—the difference between High and Low is only 77 FPS, and High provides a much better experience. Ultra at 179.4 FPS is still highly playable, and the 107.1 FPS gap between Ultra and High may not be worth the visual improvement for some players. For the best overall experience, the data suggests 1440p High as the ideal setting for this combo, with 4K High as the alternative for those prioritizing resolution over raw frame rate.
